The annoying bee-sounding vuzuzelas that have been dominating the World Cup coverage will be banned from T In The Park, organisers say.
Anybody found with the instrument will have them confiscated festival chiefs have warned.
In an email to ticket holders, bossed said that the horns "were not suitable for a music festival."
T In The Park 2010 will take place at Balado Airfield, Scotland from 9-11 July.
Tickets have sold out but there are a number of passes available on secondary ticketing platform viagogo, both for individual days and for the weekend, currently starting at £187.50 for all three days.
viagogo will provide a safe and secure online platform enabling fans to sell spare tickets if they are unable to attend. viagogo guarantees every transaction meaning that buyers can be sure they will get the tickets they paid for, and that sellers will get paid for their tickets.
